In the social practice of the third unit of mathematics in the sixth grade of primary school, let students carry out social practice, and the content is the golden section. In this regard, I made a further analysis of the golden section and found out the golden section in daily life, which is an ancient mathematical method. Its magical functions and magic power have not been clearly explained in mathematics so far, but in practice it is found that it often plays an unexpected role.
(1) golden section in human aesthetics If a person's navel to toe is 0.6 18 of his total length. The navel to the head should be 0.382 of a person's total length, which is the golden section. Such a person is a standard figure.
(2) The golden section in webpage color matching. When making a web page, it is troublesome to match the font colors of the background and foreground of the web page. If the matching of background color and font color is unreasonable, the effect of the web page will be greatly reduced. If the contrast between the background color and the font color is too big, it will be too dazzling; The golden section method adjusts the color contrast (background and foreground) to the ratio of 0.6 18. It can be seen that the golden section also reflects its magical role in modern life.
(3) The golden section in photography. A photographer must realize that the golden section is a law that can be widely used in photographic composition. In a good work, composition is pleasant, but there are actually many places where the golden section is hidden.
(D) product design and the golden section. In product design, how to determine the proportion of products, so that product modeling has more visual aesthetic thinking and application. It also hides the golden section.
(E) Diet structure should also follow the golden section. The golden section law is the law of nature. Humans should live a long and healthy life, and the diet structure should return to nature. Vegetarian food should account for 0.6 18 of the total food. In some developed countries, animal food is the main dietary composition, which reverses the golden section and leads to an increase in the incidence of "civilized diseases" such as cardiovascular disease, diabetes and obesity. The most healthy thing is that carbohydrate heating accounts for 0.6 18, mainly starch in grains, so grains should be the staple food.
(VI) Application of the golden section rate in the stock market "The golden section rate" is applied to the stock market analysis, and it is found that when the rising speed of the stock index or stock price reaches 0.382 times or 0.6 18 times of the previous wave band decline, it will generate a large back pressure and may stop rising and falling at any time; When the stock index or stock price falls, when the falling range reaches 0.382 or 0.6 18 times of the previous band, it will have great support and may stop falling and rise at any time. Using "golden ratio" to predict the trend of stock index or stock price will greatly improve the profitability of stock investment.
(VII) Health preservation and golden section 0.6 18 also plays an important role in health preservation. Paying attention to these golden sections is of great benefit to health and fitness. Dynamic and static: From a dialectical point of view, the dynamic and static ratio is 0.6 18. Diet: medical experts also found that people who eat 60% to 70% of a meal have almost no stomach problems; The proper diet is six portions of coarse grains and four portions of refined food. Marriage: According to the golden section law, the best season for marriage is 0. 18 in a year, from the end of July to the end of August. Medical research shows that autumn is the golden season of human sexuality and immunity. Because there are the most lymphocytes in human blood from July to August, a large number of lymphatic factor resistant to various microorganisms can be produced. At this time, people have strong immunity and are less likely to get sick.
